Nature and Obfe'cts of thelavention.

Thefnst part of my invention relates to the useof a triangular frame for holding concavo-couvex eultiv.

The ratchet-bar It should be boltc of frame A, so as not to interfere with the expansion or contraction of the frame at its rear .end, laterally.

The lapping ends of the sides of frame, A should be held together at this pointbyboltsand nuts, and should have a series of holesythrough each, so as to admit of widening or narrowingof the frame at-its rear end. But this same result maybe attained by moving the disks B B (on each side) forward or backward on the frame with movable brackets, thus narrowing or widening the lateral position of the disks B B on one side from those on the other, by reason of the V-shape of the ii'ame.

This machine is very light, easily drawn, does its work thoroughly, and can be managed as readily as a sh ovel-plo\v.

What I claim is-- 1L cultivator or barrow, composed of the wave-sided frame A, disks B B and O, the toggle E, and handle P, in connection with ratchet-bar It, arranged, comblood, and co-operating in the manner described, and
